Complete Virtual Reality and Augmented Reality Development with Unity

By: Jesse Glover, Jonathan Linowes

Overview of this book

Unity is the leading platform to develop mixed reality experiences because it provides a great pipeline for working with 3D assets. Using a practical and project-based approach, this Learning Path educates you about the specifics of AR and VR development using Unity 2018 and Unity 3D. You’ll learn to integrate, animate, and overlay 3D objects on your camera feed, before moving on to implement sensor-based AR applications. You’ll explore various concepts by creating an AR application using Vuforia for both macOS and Windows for Android and iOS devices. Next, you’ll learn how to develop VR applications that can be experienced with devices, such as Oculus and Vive. You’ll also explore various tools for VR development: gaze-based versus hand controller input, world space UI canvases, locomotion and teleportation, timeline animation, and multiplayer networking. You’ll learn the Unity 3D game engine via the interactive Unity Editor and C# programming. By the end of this Learning Path, you’ll be fully equipped to develop rich, interactive mixed reality experiences using Unity. This Learning Path includes content from the following Packt products: • Unity Virtual Reality Projects - Second Edition by Jonathan Linowes • Unity 2018 Augmented Reality Projects by Jesse Glover

Playing with Mixed Reality

Let's begin by first downloading the model we will be using with this project. Once again, let's follow these steps:

Go to turbosquid.com and type scifi as the search parameters:

Next, change the pricing to Free:

Find one you like. I like robots and I use FBX format, as I find it easy to use with multiple projects and game engines. So, I will select this one:

It will take you to a download page, so make sure you select the correct file you want and if it has a textures folder, download that as well:

Download robot

Go to the folder where you downloaded the zip file and extract it:

Now we can jump into Unity. Create a new project and I will call this one Chapter8:

Create a new folder called Models:

Import the model into the project:

We now need to go through the steps to install the HoloLens Emulator. I should note that this will only work for Visual Studio, 2015 edition. If you have Visual Studio 2017 or later, you can use the Mixed Reality simulator that is built into the...
